Specification of I.etters Patent.

Patented Aug. 24, 1920.

Application filed August 24, 1914, Serial No. 858,386. Renewed December 31, 1919. Serial No. 348,541.

' To all whom it may concern:

tics, but provided wit Be it: knowffthat I, JACOB W. ELVYN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Indicators, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to memorandum indicators for making notes in the way of reminders, or making records for temporary preservation, and is concerned with an. improved construction and arrangement of parts, to the endof simplicity, economy and durability.

It will appear to those skilled in the art that my invention may be employed for a large number of different purposes where memoranda, or temporary records, are desired, but for the purposes of this disclosure I shall illustrate and refer to certain uses which I find most popular.

Accordingly, I have illustrated a laundry record, and a household reminder, each having the same eneral characterisspecial features characteristic to its species.

In the accompanying drawings- Figure 1 illustrates a laundry record;

Fig. 2 shows an enlarged detail of this indicator.

It will be seen that I provide a front card a and a rear card I) which are secured together by a plurality of regularly. arranged eyelets 0. Upon each of the eyelets, between the two cards, a circular indicator disk at is mounted, and one of these disks is shown in full detail in Fig. 2 where it willbe seen that it is provided with a plurality of circularly arranged numerals, any one of which is adapted to be exposed through an open inge in the front card, such an opening being provided, for each disk. The openings shown.

It will be seen that each of the disks d extends slightly beyond the edge of the cards :so that the disks may be engaged by ones finger at that point and moved to expose any of the numerals thereon through the corresponding opening 6. Opposite the zero point 00 of each of the disks, the disk is provided with a peripheral notch y which is thus exposed in the protruding part. of the disk at the time that the zero point is exposedthrough the corresponding opening 6. Thus, merely by the sense of touch,'one may speedily bring all the disks back to the zero point, determined when one feels the notch in the protruding part of each of the disks, the periphery of the disk being otherwise smooth. In order that this relation may exist with the conditions above described, the openings 0 are placed in line with the pivot rivets 0. 1

I claim as new, and desire to secure by Letters Patent of the United States: I In a memorandum indicator, a card having a small opening therein, a circular disk pivoted thereon and disposed so that the disk protrudes beyond the edge of the card where it may be engaged, said disk being provided with a series of numerals adapted to be successively exposed through the small opening in the card by turning the disk, and said disk having a peripheral notch disposed so that it will be in the protruding part of the disk When' the zero point of the disk is exposed through said small opening, the periphery of the disk bein otherwise circular. In witness whereof, hereunto subscribe my name this 21st day of August, A. D. 1914.
